How good are carbon contacts for MIS structures compared with other metal contacts like Ni, Au and Al?

To perform electrical measurements on thin film devices, we always need ohmic metallic contact electrodes. The most commonly used metals are Au and Al. I would like to use carbon paste but I have...

How does the bias voltage affect/influence impedance properties of a MOS structure?

I have done impedance measurements of a metal-oxide-semiconductor structure as a function of the bias voltage. The radius of the impedance arc in the Nyquist plot decreases with and increase in...

How can I calculate film thickness and refractive index from UV-vis reflectance and/or transmittance data only, without interference fringes?

For thicker homogeneous films, the optical reflectance and transmittance spectra show several interference patterns which can be used to obtain optical constant using Swanepoel and other related...

Is it possible to measure transistor output and transfer characteristics using Autolab setup?

I am preparing to start working on thin film transistor (TFT) devices from metal oxides. In literature I have seen most people use semiconductor parameter analyzers for measuring drain current as...

How is the droplet size in an aerosol in a spray pyrolysis experiment calculated?

I sprayed my samples by nebulizing/atomizing a precursor solution of InCl3 salt dissolved in ethanol solvent. I would like to know the size of the aerosol droplet. Is there a way of calculating...

How does the stoichiometry of a host semiconductor affect diffusion of a foreign atom?

I am investigating diffusion of Cu in In2S3 layers with and without chlorine and the activation energies and pre-exponential factor D0 are different for the two sets of layers. Structural...

How can one determe the ionization potential directly using UPS/XPS? Is it possible to show this directly on the UPS/XPS spectra? If so, then how?

I know ionization potential can be obtained by adding the work function to the valence band maximum, which can be both determined directly from a UPS/XPS spectra. I was wondering if this is...

Is it possible for two human neuronal cell lines to have different gene sequence for the same protein?

I am looking at the ATP1A2 (Sodium/Potassium ATPase alpha subunit 2) in two human neuronal cell lines. Expression levels of this protein seems to be almost equal when detected by one antibody....
